Specification of Letters Patent.

Patented Mar. 8, 1921.

Application filed October 11, 1919. Serial No. 330,064.

To all whom itma/g/ concern:

Be it known that I, CLARENCE E. GERBE- RICH, a citizen of the UnitedStates, residing at Aurora, in the county of Kane and State of Illinois,have invented a certain new and useful Improvement in Trays, of whichthe following is a specification.

My invention relates to trays, boxes and similar open top receptaclesespecially those formed of sheet metal and intended for use underindustrial conditions where the devices will be subjected toconsiderable strain and rough usage. The object of myinvention is toconstruct a tray in such manner that there will be no waste material orscrap and that each and every portion of the blank shall contribute in ahighly efficient manner to the strength and durability of the articleespecially at the corners.

I accomplish my ob 'eots by the cons-truction illustrated in theaccompanying drawings in Which' Figure 1- is a perspective view of thecomplete tray or pan. 7

Fig. 2 is a perspective view taken from beneath the tray, looking at onecorner thereof and showing the lap at the top of the side previous tofolding.

Fig. 3 is a sectional view onthe'line 33, Fig. 1.

Fig. 4 is a. sectional view on the line 44, Fig. 1.

Fig. 5 is a sectional view on the line 5-5, Fig. 1, and

Fig.6 is a face view of the blank.

Like numerals denote like parts throughout the several views.

The principal parts of the tray are the bottom 1, sides 2, 2 and ends 3,3. The bottom is integral with the sides and with the ends, but thesides are severed from the ends by cuts indicated by the solid lines a,a, a, a, Fig. 6. These cuts run from the corners of the bottom sectionoutward toward the edges of the side sections. They slant slightlytoward the corners of the blank in order to give the finished tray aslight taper, although this is not essential, and the tray may havevertical sides without departing from the spirit of the invention. Byreferrin to Fig. 6 it will be evident that when tha blank is thus cutthe end pieces will have extensions at each of their ends, saidextensions affording stock which may be folded in the particular mannerwhich I will now de scribe. i

lVhilethe precise order in which the folds are made may not beessential, it is possible and practical to proceed by first folding thecorners of the blank along the dotted lines 1), 725 This makes a doublethickness of metal which, as will later appear, comes both at the sidesand at the ends of the tray and gives a corner bend of double thickness.Next the sidepieces and end pieces are bent to upstanding position,after which the extensions of the end pieces are folded around the sidepieces as clearly illustrated .in Figs. 1 and'2. By bringing thelines'b, b in far enough toward the median line 0 of the tray, thedouble thickness of metal'will not all come at the sides of the tray,but part of it will bend around the corner and come at the ends of thetray, as illustrated at 5, Figs. 1 and 2. After the parts havethus beenfolded and preferably fastened by spot welding or riveting theupstanding margins 6 of the side pieces (see Fig. 2) will be foldedoutward and downward from the position shown in Fig. 2 to thepositionshown in Figs. 1' and 5. This interlocks the parts as well aspresenting a finished appearance and stiffening the sides of the tray.Handles are formed bybending outward, to an approximately horizontalposition, the margins 7 of the end pieces. As the handles preferablyextend from one side of the tray to the other there will be a portion 8at each end which is of double thickness, due to the first back-foldingalong the lines 6, b. The resulting advantage is that the handles aremore rigid and raw corners at their ends are avoided. It isv desirablealso to form a half inch lap 10 at the outer edge of the handles forstifiening them and presenting a rounded edge.

Reference to Fig. 1 will show that the metal is used most advantageouslyand produces a tra having great strength and durability. ot only do theend pieces extend around to the sides of the tray thus making acontinuous piece at the tray corners, but for a considerable portion ofthe vertical dimension of the tray, at the corner, the material is ofdouble thickness. In fact, this double thickness comes at the upperportion of the tray Where the strainer leverage will naturally be thegreatest.

ners are heavily reinforced and the material is located where it will dothe most good.

It will also be noted that the extensions which overlap the sides of thereceptacleare of substantial length and pass closely beneath themarginal flange 6, thus affording "a leverage for l'BSlStlIlgOHtWZtIClswing of the ends of the receptacle.

Having thus described my invention what- I claim as new and desire tosecureby-Let ters Patent, is

1. A sheet metal tray formed from 2. rectangular blank having singlecuts running from each corner of the bottom section outward to the topedge of the side piece, the cuts being'taken at a slight angle to permitthe sides of the tray'to slant slightly out Ward, the end piecesconsequently having extensions at their ends terminating in the sides oftheblank, the outer corners of. the end pieces of the blank being foldedback to lap against the outer surface of the end piece, and in thefinished tray,the extensions being folded around the corners to thesides of the'tray, whereby outward pressure against the sides of thetray is resisted.

2. A structure asspecifiedinclaim l inwhich the double thickness due tothe backfolding at the corners of the blank not only comes at the sidesof the tray butalso to some extent at the ends'whereby the corners ofthe tray have continuous metal .ofdouble thickness rounding the cornersfor a portion of their height.

A sheet metal tray or tote boxhaving 4 sides and ends which are integral with the bottom, thesideshaving marginal flanges '6 and the ends having extensions ofsubstantial depth. which are of double thickness for such length, that.the double thickness comes both at the ends and at the sides, the saidextensions passing for asu bstantial distance along the sidesof the boxand in close'proxv imlty to the. said marginal flange,- whereby aleverage is provldedfor resist ng outward swing of the box ends.

5. A one piece sheet metal tray including a bottom, sides, andends,extens1ons on ends folded back uponZthemselves on'a line atan angleto any marginal edge of said tray to provide portions of doublethickness extending throughout a substantial part of the depth of saidextensions, said extensions being folded in overlapping relation to thesides whereby'the corners and portions of both the sides and ends adacent the corners are of double thickness, and means securing said sidesand ends against relative outward movement. v
